This is a putter designed for score improvement by Izumi Kuwata, the creator of the Quarter Theory, and Koji Hoshitani, a golf science researcher. It's a pin-type putter from the Zeus series. It's a very cool-looking putter. Details include a traditionally milled head form of an Anser-type putter, surface detailing, and a head designed for absolute squareness and weight. The putter is designed to make it easy to gauge distance, with a focus on the balance of total weight, head weight, and shaft weight. This is a high-end putter that was sold at EAGLE 18 for 89,000 yen. Length: 34 inches (actual measurement 90cm) Shaft: Genuine Grip: ROYAL GRIP Putter Cover: Genuine There are some minor scratches, but I think it's in good condition. This is a very rare item, so it's likely difficult to obtain. Please check the photos for the condition. This is a used item, so please refrain from purchasing if you are overly concerned about its condition. #IzumiKuwata #QuarterTheory #Titleist #TaylorMade #Callaway
